Application filed November 30.1925. Serial m. 72,270.

My invention relates to apparatus for making imprints as a class.

The object of my invention is to provide such a device particularly intended for imprinting labels and designs upon wrapping paper during the time the paper is being colored in a bath of coloring liquid, the apparatus having a roller provided with removable plates thereon adapted and arranged to allow the roller to make imprints and the paper to pass under the roller and under pressure so that it will emerge with three tints or shades. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the drawings which form a part hereof.

Fig. I is a front elevation of the imprinting roller with inserted plates and with parts broken away.

Fig. II is an enlarged sectional view of part of the roller and imprinting plates in- Fig. I. Fig. III is a detail plan View of the plate fastener in operative position.

A frame 1 supports a tank 2 and the standards 3 and 4. In the standard 3 are guides 5-6, having oppositely disposed bearings 7,8 transversely positioned on each side of the tank and at convenient heights.

In the lower bearings 8 aroller 9 of rubber or other material of like nature is rotatably mounted. Above said roller'a second metal roller 10 is rotatably mounted. The rollers are slipped into their bearings and removed therefrom through the guides. A pulley 11 is connectedwith the shaft of the roller 9 when the same is in place, and a belt 12 extends from the pulley to a' power source.

Above the journals of the roller 10 pressure.

screws 13 are arranged in the standard 3, with compressionfsprings 14, to press the roller 10 to a desired, engagement with the lower roller 9. In the roller 10 arep t'e receivin recesses 15, arrangedinserie's-about the ro er. At eachend of the recesses 15 therein.

are small recesses 16, threaded in their upper portions. A screw plug 17 ,having a longitudinal groove 18, is adapted to be screwed into the recess 16. A fastener 19, having a coil spring 20 on its lower portion and an eye 21 on its upper end, is slidable intothe groove 18, adapting the spring portion of the fastener to be positioned in the recess 16 with the neck of the fastener extending above the plug, the spring engaging the lower surface of the plug and retainin the fastener eye. upon the upper surface'o the plates. Liners 22 are placed within the recess 15 to cause the plate surface to extend beyond the plane of the roller surface a, predetermined distance. Imprinting plates 23: are provided, having a curvature in al1gn'-' ment with that of the roller. The plates have angled ends 24 and grooves 25 in each of these ends to admit the fastener eye 21 When the plates are laid upon the linersin the recesses15, pins 26 are inserted through the fastener eyes and the springs 20 then retain the pins in engagement with the plate ends and thus retain the plates'in operative position on the roller. A marginal space is left between the upper plane edges of-the plate 23 and the opposing walls of the recess'15. Rollers 10 with. recesses 15 of varying dimensions are provided to receive plates of corresponding relative dimensions, bearing different imprinting characters and designs. In the standard are mounted wringer rollers 27 of rubber and 28 of metal, with pressure "screws 29 above, having compression springs 30 to force the sald rollers into engagement. Near one end of the tank is a standard 31 adapted to receive the shaft 32 holding a paper roll 33. Guide rollerp 34 are positioned to;carry the paper from he' roll 33 into the tank, to the imprint rollers, from them to the wringer rollers andfrom the latter to a drying place. Afselected color fluid 35 is placed in the tank. The course of the paper through I the apparatus is indicated by arrows in Fig.

The plates have'integral engraved designs or characters in their surfaces, as illustrated in Fig. I, recessed in them. v

The operation will now be described. A coloring liquid of any desired kind isplaced in the tank, thelevel thereof being below the lower surface of the roller 10. The imprint forms ofthe plates arecut or re'ce'sse'din them as stated. The lates 23 which are selected.

for the intend operation are placed over liners in the recesses 15 in a manner to raise the surface of the plates slightly above the adjacent surface plane of the roller 10. The

v ends of the fasteners 19 slip through the plate grooves 25 and the pins 26 are inserted in the fastener eyes 21, thus locking the plates on the roller. The roller is then shpped through the guides to the operative position shown in Fig. VI. The paper is then drawn from the roll about the guide rollers, through the rollers 9 10 and the Wringer' rollers 27-28, thence outwardly to'a convenient drying place. Power .being applied, the plates are impressed upon the paper with greater penetration of its fibre'than that of the adjacent surface of theroller. This from the color it assumes in the bath, which is [lighter than that produced}? by the'plate surfaces or rollers. Thus a margin is formed about the body 'color made by -the plate surfaces and between the same LandIthe body color ofthe remainder of the paper as made by the roller surface. By the operation of my device wrapping paper is produced of varying beautiful tintsor shades, bearing a series of imprints with"=margins about them containing advertising. matter, designs,

trade-marks, etc., all arranged in a niostat', tractive form. The apparatus has been inpractical operation and fo'undto be entirely successful in producingthe paper described, which has been accepted and used by the public to a large extent. The operation of the device is very economical, as' a few changeable rollers will accommodate an unlimited assortment of platesvarying in dimensions. Heretofore rollers with imprints engraved in them have been commonly used,

which makes the operation expensive. In

my device the plates are made at a minimum expense and thus greatly economize the operation to manufacture the paper mentioned. The single operation to produce three colors is highly advantageous in the art and trade.

The device is therefore distinctively novel and useful.

I claim: 1. Means for imprinting on paper a plurality of tones with one dye, comprising, in

combination, means for holding a quantity of dye,- impression rollers, having varying nnpresslon surfaces, mounted in proximity to the dye in said dye holding means, means meaoae forimmersing paperin the dye and passing itdirectly from the dye to and between said rollers and directly from said rollers to and through said dye a second time. 7

2. Means for imprinting on paper a pluv rality of tones with one dye, comprising, in. combination, means for holding a quantity of dye, impression rollers, having varylng impression surfaces, mounted in proxlmity to the dye in said dye holding means, means for immersing paper in the dye'and passing it directly from the dye to and between said rollers and directly from'said rollers to and through said dye a second time, and wringer rollers between which the paper is passed after it leaves thedye. 5

4:. A device for imprinting on paper a plurality of tones with one dye, comprising, in combination, a dye tank'for holding a quantity of dye, a smooth surfaced roller of compressible material mounted in hearings in said tank in position to extend below the surface of the dye -in the tank, a non-compressible roller-arranged in contact with said compressible roller, and havingvarying im pression surfaces, means for immersing paper in'the dye in'said tank and passing the same directly to and between said rollers and directly from said rollers to and through said dye a second time. I
